Investigating the dynamics of non-equilibrium quantum systems is relevant to many areas in condensed matter physics. Areas of interest include the study of superfluid turbulence, topological states, mesoscopic circuits and can even be extended to neutron star dynamics. In these systems there are many interacting entities, making exact calculations problematic. However, it is possible to theoretically and experimentally examine quantum dynamics when there are only a few quantum bodies in the system of interest. An idealised example of such a system, where few-body quantum dynamics can be studied, is harmonically trapped quantum gases, which can be constructed at the single to few atom limit [1]}, [2]}, [3]}, [4]}, [5]}. In this work we focus on the interaction quench dynamics of three fermionic atoms trapped in a spherically symmetric harmonic trap.
